Description

Technical Field

[0001] The invention belongs to the technical field of prestressed wire winding, and particularly relates to a super-large cantilever type prestressed wire winding device and method for a double-layer ring beam with a capacity of ten thousand tons. Background Art

[0002] In order to simulate the complex stress environment of deep rocks at 10,000 m underground, a Chinese patent application with the application number 202310058018.6 discloses a super-large-scale physical simulation facility for deep engineering disasters. A three-dimensional loading reaction frame structure with super-large size and high stiffness is applied in this facility. The horizontal super-large reaction frame adopts an outer-circle and inner-square ring structure, with an outer-circle diameter of 20 m, an inner-square side length of 10 m, a vertical height of 5.5 m, and a weight exceeding ten thousand tons. The horizontal frame as a whole belongs to a double-layer ring beam, and each layer of the ring beam is composed of four arched beams spliced together. In order to ensure the high safety stability and long service life of the horizontal frame, prestressed wires need to be wound around its outer circumferential surface to enhance its stiffness and ultimate tensile capacity.

[0003] Currently, existing prestressed wire winding devices are divided into turntable type wire winding devices and satellite type wire winding devices according to different wire winding methods.

[0004] For the turntable type wire winding device, first, the component to be wound with wires is placed on the rotary workbench, and then the wire output device arranged on the ground pays out the wire. As the rotary workbench rotates, the wire is wound on the component. However, for a double-layer ring beam with a capacity of ten thousand tons, it not only needs to bear a weight of ten thousand tons but also bear a huge centrifugal force during the rotation process. Therefore, it is very difficult and not easy to implement a suitable rotary workbench.

[0005] For the satellite type wire winding device, first, the component to be wound with wires is placed on the ground, and then the mobile wire output device moves in a circular motion around the component and pays out the wire, and the wire is wound on the component. However, for a double-layer ring beam with a capacity of ten thousand tons, the wire winding stability of the mobile wire output device is relatively low, and problems such as wire misalignment and gaps are likely to occur during wire winding. Therefore, it is difficult to meet the requirements of wire winding quality. Summary of the Invention

[0016] A method for winding prestressed wire of a ten-thousand-ton double-layer annular beam super-large cantilever type adopts the ten-thousand-ton double-layer annular beam super-large cantilever type prestressed wire winding device, and comprises the following steps:

[0017] Step 1: Install the slewing drive mechanism at the center of the foundation pit; complete the assembly of the double-layer ring beam main structure around the slewing drive mechanism; install the cantilever beam on the slewing drive mechanism; complete the installation of the stay cable reinforcement structure and the balance weight structure on the cantilever beam; install the first vertical arm on one end of the cantilever beam through the first horizontal sliding table mechanism, and install the second cantilever on the other end of the cantilever beam through the second horizontal sliding table mechanism; install the first manipulator and the second manipulator on the first vertical arm through the first lifting sliding table mechanism, and install the third manipulator and the fourth manipulator on the second cantilever through the second lifting sliding table mechanism; install the first wire wheel on the first manipulator, and install the first tension regulator and the first wire arranging device on the second manipulator; install the second wire wheel on the third manipulator, and install the second tension regulator and the second wire arranging device on the fourth manipulator;

Draw out the wire from the second wire wheel, connect the drawn wire to the second tension regulator and the second wire arranging device in sequence, then draw out from the second wire arranging device and connect it to the lower ring beam for fixation;

[0020] Step 4: Send control instructions to the first tension regulator and the second tension regulator through the PLC controller. Tighten the wire connected to the upper ring beam through the first tension regulator until the tension value of the wire reaches the preset prestress; tighten the wire connected to the lower ring beam through the second tension regulator until the tension value of the wire reaches the preset prestress;
